Product Configuration Model - Performance Advise

(0) ShareShare
ReportReport
Posted on by new_axys 135

Hi Community,

So i built a medium sized Configuration Model for a Customer (6500 Attributes, 50 Table Restrictions, 25 Sub Components, lots of Calculations) and we re experiencing real Problems with Performance. To start up the Model and the first initiation in regards to, what to show and what to hide from the start off it takes up to 2 minutes to apply all the rules.

Now i know the Cache does SOME work in performance increase, but maybe some of you have other advise. It would be much appreciated.

regards. Ruben

    Hi Ruben,

    When working with product configurator, you should have R3 version to make sure you work with latest version of caching mechanism.  If you have R2, make sure you have at least hotfixes provided by KB2969969.

    Some perfomance issues can be caused by tree redraw.  You can declare an integer variable in PCRuntimeConfigurator class and use dispose method to display the content of it to infolog.  The variable can be incremented in class PCRuntimeUIConfigurator (method componentModifierChanged).  If the tree is redrawn more than 2 or 3 times, then you should consider doing a customization to minimize these redraw.  A suggestion here would be to use setTimeOut to do a redraw only once at the end of the loading process.

    Another time consuming task is within PCRuntimeConfigurator.parseXmlModel.  Even if XML caching option is activated, it can take many seconds to parse XML structure to build an instance of runtimeModel.  Again, a customization can be useful.  A suggestion here would be to use Infolog.globalCache() to store and reuse an instance of runtimeModel.

    Hope this helps.

    Hi. Thanks - there is some usefull advise. I think my biggest Problem is a massive Calculation which has about 40 "if"s in it :D its hard though to work around, tough request by the customer .

    I now geat System.out.of. memory all the time , its very frustrating and simply can not be debugged.

    I don't know if it's possible to debug this part since we don't have access to the source code of product configuration dll.

    Have you already considered using custom x++ code to replace the calculation ?  In class PCRuntimeConfigurator (method valueChangedEventHandler), you could catch a specific attribute, call your custom method, and then call method assignAttributeValue to send back to the dll another attribute value.

    Just keep in mind that inserting customizations in this area can lead to performance degradation and/or instability.

    are the attributeInstanceId´s static ? so i simply debug, identify the attributeInstanceId and write my code?

    AttributeInstanceId are not static.  They can be different after clearing xml caching.  And they are not the same across multiple environments.

    You will need to check attribute name through runtimeModel.getAttributeFromId().  However, an attribute name is not necessarily unique within a model.  So you may need to customize class PCRuntimeAttribute and/or PCRuntimeXMLParseAttribute to add more info (ie extended solver name) in attribute class.

    You may also need to customize PCRuntimeModel because you will need a way to get attribute id from an extended solver name.  Id is required when calling AssignAttributeValue for attributes affected by custom calculations.

    thank you for that. in our case, the values to be calculated are in the MAIN component, so there kinda unique.

    i have coded all day yester day :D couldnt debug though, still getting system out of memory for no obvious reasons :D will inform if solution found
